摘　　要：采用双波长LED作为检测光源,其中254 nm波长受CODUV、浊度和色度影响,398 nm只受浊度和色度影响。通过吸光度计算,得到CODUV值。该检测仪具有结构简单、体积小、能耗低、稳定度高、模块化结构设计、易集成的特点,是新一代的CODUV水质在线监测设备。A dual-wavelength LED is used as the detection source. The 254 nm wavelength is affected by CODUV, turbidity and chromaticity. The 398 nm is only affected by turbidity and chromaticity. The CODUV value is obtained by calculating the absorbance. The detector has the characteristics of simple structure, small volume, low energy consumption, high stability, modular structure design and easy integration. It is a new generation CODUV water quality online testing equipment.
